ANTFFROSTING DEVICE.

' Application 1ed` March 7 To all whomvft may concern.'

Be it known that l, FRANK SCHOiiIGER, a

citizen ofthe United States, residing atk Kingstom'in the county of Ulster, State of New York, have invented a new and useful Device; and I do hereby declare the fo lowing to be -ga full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the'same.

The invention is an anti-frosting device designed for use on the wind shields of automobiles, front windows' of street cars, or other places where such a device is: serviceable.

The principal object is to providea means for keeping` wind shields or car windows free from frost or moisture that would obstruct the View through them. v

A further object is to provide, in such a device, means that will permit it to be shiftedtto various different positions on the tailed description of'this device which is to window or shield to which it is applied. z A further object is toprovide a novel means for supporting the device on a wlnd shield.

lOther objects will appear from the defollow.

'The drawings set forth a specific embodiment of the invention to which, h owever, 1t is notto be restricted. The right ,1s reserved l to vary the details of this embodiment to any extent permittedpby the scope of the ap# pended claim. I

In illustrating this inventionno pretense is made to correct proportion. Practical trials have shown that the device itself may 'be comparatiJ/ely small*with,respect tothe wind shield or window which it is to protect from frost As shown on the-drawings, the

device lis disproportionally large with re-` spect to-the wind shield to which it is'attached, but has been made so to more clearly 'illustrate the device.

=A uniform system obtains throughout the drawings for designating the various parts -in the, several figures.-

Fi" re 1 is a plan of the invention, show- Aing 1t applied to the conventional wind shield. l A Fig. 2 is also a plan view, but shows device viewed from the opposite side, glass beingl omitted.

' Fig. 4 is a section on the line of Fig.` 3.

wind shield having the surrounding frame 2. The clamp 3 is adapted for attachment to the frame 2, this clamp supporting the rod 4. Y The clamp comprises two members, the eye bolt '6, the sleeve' member 7 and vknurled nut 8. rlhe eye bolt 6 is adapted to .is designed to rest and also has a'slot 9 to permit thellower half of the head of the eye bolt 6 to enter it. The members have curved ends which are adapted to encircle The numeral 1 represents a conventional Patented June 5, .1917. I,

the frame 2, the straight extensionsof these curved ends being provided with holes through which the shank of the eye bolt 6 passes.

As shown in Fig. 3, when the members 5 A are so positioned that their curved ends envcircle the frame 2, the nut 8 may be tightened by screwing it up on the shank of the eye bolt 6. This operation causes the head of the eye bolt'l to press Adown on the rod 4 .which in turn presses on the sleeve member 7 causing the latter to press upon one ofthe members 5, the other member `5 being` pressed upon by the knurledfnut 48. The

Ascrewing up of the nut 8 thusoperates to secure the rod 4 to the clamp 3 andthe clamp 3. to the frame 2. i

l The rod 4 attaches to a lpost 11 a diametrically disposed hole to engage the rod in slidin relation thereto`,a screw 12 being provide to secure the post tothe rod when the desired position of the post on the rod has been obtained.- A plate 10 is fixed 'tothe post" 11 by any-suitable method of attaching (it thereto; The sides and ends of the ,plate 10 are turnedv at right angles to its body forming theflanges 13 and 14. A suitable insulating plate 16 rests between the flanges 13' and 14, the ange's 14 being turned Depressions 15 'are made also in the anges 1'3 to further securethevinsulation 16. A suitable heatingcoil 17 rests upon Y which has ius this insulation: 16 to hold it in the insulation 16' and is connected between the Wind shield is apparent, when it is re- Y the binding posts 1,8, these, binding posts passing through the plate flO and being suitably insulated therefrom. Conducting Wires 19 connect with the binding posts 18 and operate to transmit electric 'current (from any suitable means of supply) to the heating coil 17.

Thedevice operates by keeping the Wind shield (to Which it is applied) heated, so that frost cannot accumulate thereon, the heat being obtained by electric current. It Will be seen that the clamp 3 can be shifted in position on the frame 2 and that the rod 4 can have its position changed With respect to-the clamp. Therefore, the heating member can be shifted to any desired position on 'the Wind shield to keep any desired portion .of the latter free from frost.

The advantage of providing means for shifting the device to various positions on membered that in eXtreme WeatherF the device may not be able to radiate enough heat A to keep all the Wind shield free from frost.

Under such conditions the device can be po-l sitioned to keep a certain'definite area clear, to permit an unobstructed view ,to the driver.

The device may be applied in any other caseA Where anti-'frosting vmeans is serviceable, such as street car Windows and the like, a supporting rod being positioned, so that the clamp 3 may be conveniently applied thereto.

What is claimed is:

In an anti-frosting device, a heating coil, a supporting plate for the heating coil, a post attached to said plate, a rod connected With said post, and a clamp connected with said rod,the post having means for changing the position of the plate and the heating coil with respect to the rod, the clamp and for simultaneously securing the rod to it, the clamp being further provided with 'means to permitlthe position of the rod to be varied longitudinallyor angularly with respect to it.

In `testimony whereof I have signed my name to thisspecifcation in the presence ofy two subscribing Witnesses.
